Some of us -- myself included -- have proposed lawful government hacking as an alternative to backdoors. A new report from the Center of Internet and Society looks at the security risks of allowing government hacking. They include:
Disincentive for vulnerability disclosure
Cultivation of a market for surveillance tools
Attackers co-opt hacking tools over which governments have lost control
Attackers learn of vulnerabilities through government use of malware
Government incentives to push for less-secure software and standards
Government malware affects innocent users.
These risks are real, but I think they're much less than mandating backdoors for everyone. From the report's conclusion:
Government hacking is often lauded as a solution to the "going dark" problem. It is too dangerous to mandate encryption backdoors, but targeted hacking of endpoints could ensure investigators access to same or similar necessary data with less risk. Vulnerabilities will never affect everyone, contingent as they are on software, network configuration, and patch management. Backdoors, however, mean everybody is vulnerable and a security failure fails catastrophically. In addition, backdoors are often secret, while eventually, vulnerabilities will typically be disclosed and patched.
The key to minimizing the risks is to ensure that law enforcement (or whoever) report all vulnerabilities discovered through the normal process, and use them for lawful hacking during the period between reporting and patching. Yes, that's a big ask, but the alternatives are worse.
Abstract: We demonstrate that an Internet of Things (IoT) botnet of high wattage devices -- such as air conditioners and heaters -- gives a unique ability to adversaries to launch large-scale coordinated attacks on the power grid. In particular, we reveal a new class of potential attacks on power grids called the Manipulation of demand via IoT (MadIoT) attacks that can leverage such a botnet in order to manipulate the power demand in the grid. We study five variations of the MadIoT attacks and evaluate their effectiveness via state-of-the-art simulators on real-world power grid models. These simulation results demonstrate that the MadIoT attacks can result in local power outages and in the worst cases, large-scale blackouts. Moreover, we show that these attacks can rather be used to increase the operating cost of the grid to benefit a few utilities in the electricity market. This work sheds light upon the interdependency between the vulnerability of the IoT and that of the other networks such as the power grid whose security requires attention from both the systems security and power engineering communities.
I have been collecting examples of surprising vulnerabilities that result when we connect things to each other. This is a good example of that.
Abstract: We report the first active acoustic side-channel attack. Speakers are used to emit human inaudible acoustic signals and the echo is recorded via microphones, turning the acoustic system of a smart phone into a sonar system. The echo signal can be used to profile user interaction with the device. For example, a victim's finger movements can be inferred to steal Android phone unlock patterns. In our empirical study, the number of candidate unlock patterns that an attacker must try to authenticate herself to a Samsung S4 Android phone can be reduced by up to 70% using this novel acoustic side-channel. Our approach can be easily applied to other application scenarios and device types. Overall, our work highlights a new family of security threats.
Suprising no one, the security of police bodycams is terrible.
Mitchell even realized that because he can remotely access device storage on models like the Fire Cam OnCall, an attacker could potentially plant malware on some of the cameras. Then, when the camera connects to a PC for syncing, it could deliver all sorts of malicious code: a Windows exploit that could ultimately allow an attacker to gain remote access to the police network, ransomware to spread across the network and lock everything down, a worm that infiltrates the department's evidence servers and deletes everything, or even cryptojacking software to mine cryptocurrency using police computing resources. Even a body camera with no Wi-Fi connection, like the CeeSc, can be compromised if a hacker gets physical access. "You know not to trust thumb drives, but these things have the same ability," Mitchell says.
Long and interesting story -- now two decades old -- of massive fraud perpetrated against the McDonald's Monopoly sweepstakes. The central fraudster was the person in charge of securing the winning tickets.
The military is an impossible place for hackers thanks to antiquated career management, forced time away from technical positions, lack of mission, non-technical mid- and senior-level leadership, and staggering pay gaps, among other issues.
It is possible the military needs a cyber corps in the future, but by accelerating promotions, offering graduate school to newly commissioned officers, easing limited lateral entry for exceptional private-sector talent, and shortening the private/public pay gap, the military can better accommodate its most technical members now.
The Diqee 360 robotic vacuum cleaner can be turned into a surveillance device. The attack requires physical access to the device, so in the scheme of things it's not a big deal. But why in the world is the vacuum equipped with a microphone?
Police in Detroit are looking for two suspects who allegedly managed to hack a gas pump and steal over 600 gallons of gasoline, valued at about $1,800. The theft took place in the middle of the day and went on for about 90 minutes, with the gas station attendant unable to thwart the hackers.
The theft, reported by Fox 2 Detroit, took place at around 1pm local time on June 23 at a Marathon gas station located about 15 minutes from downtown Detroit. At least 10 cars are believed to have benefitted from the free-flowing gas pump, which still has police befuddled.
Here's what is known about the supposed hack: Per Fox 2 Detroit, the thieves used some sort of remote device that allowed them to hijack the pump and take control away from the gas station employee. Police confirmed to the local publication that the device prevented the clerk from using the gas station's system to shut off the individual pump.
Last week, a story was going around explaining how to brute-force an iOS password. Basically, the trick was to plug the phone into an external keyboard and trying every PIN at once:
We reported Friday on Hickey's findings, which claimed to be able to send all combinations of a user's possible passcode in one go, by enumerating each code from 0000 to 9999, and concatenating the results in one string with no spaces. He explained that because this doesn't give the software any breaks, the keyboard input routine takes priority over the device's data-erasing feature.
I didn't write about it, because it seemed too good to be true. A few days later, Apple pushed back on the findings -- and it seems that it doesn't work.
This isn't to say that no one can break into an iPhone. We know that companies like Cellebrite and Grayshift are renting/selling iPhone unlock tools to law enforcement -- which means governments and criminals can do the same thing -- and that Apple is releasing a newfeature called "restricted mode" that may make those hacks obsolete.
Grayshift is claiming that its technology will still work.
Former Apple security engineer Braden Thomas, who now works for a company called Grayshift, warned customers who had bought his GrayKey iPhone unlocking tool that iOS 11.3 would make it a bit harder for cops to get evidence and data out of seized iPhones. A change in the beta didn't break GrayKey, but would require cops to use GrayKey on phones within a week of them being last unlocked.
"Starting with iOS 11.3, iOS saves the last time a device has been unlocked (either with biometrics or passcode) or was connected to an accessory or computer. If a full seven days (168 hours) elapse [sic] since the last time iOS saved one of these events, the Lightning port is entirely disabled," Thomas wrote in a blog post published in a customer-only portal, which Motherboard obtained. "You cannot use it to sync or to connect to accessories. It is basically just a charging port at this point. This is termed USB Restricted Mode and it affects all devices that support iOS 11.3."
Researchers havedisclosed a massive vulnerability in the VingCard eletronic lock system, used in hotel rooms around the world:
With a $300 Proxmark RFID card reading and writing tool, any expired keycard pulled from the trash of a target hotel, and a set of cryptographic tricks developed over close to 15 years of on-and-off analysis of the codes Vingcard electronically writes to its keycards, they found a method to vastly narrow down a hotel's possible master key code. They can use that handheld Proxmark device to cycle through all the remaining possible codes on any lock at the hotel, identify the correct one in about 20 tries, and then write that master code to a card that gives the hacker free reign to roam any room in the building. The whole process takes about a minute.
The two researchers say that their attack works only on Vingcard's previous-generation Vision locks, not the company's newer Visionline product. But they estimate that it nonetheless affects 140,000 hotels in more than 160 countries around the world; the researchers say that Vingcard's Swedish parent company, Assa Abloy, admitted to them that the problem affects millions of locks in total. When WIRED reached out to Assa Abloy, however, the company put the total number of vulnerable locks somewhat lower, between 500,000 and a million.
Patching is a nightmare. It requires updating the firmware on every lock individually.
And the researchers speculate whether or not others knew of this hack:
The F-Secure researchers admit they don't know if their Vinguard attack has occurred in the real world. But the American firm LSI, which trains law enforcement agencies in bypassing locks, advertises Vingcard's products among those it promises to teach students to unlock. And the F-Secure researchers point to a 2010 assassination of a Palestinian Hamas official in a Dubai hotel, widely believed to have been carried out by the Israeli intelligence agency Mossad. The assassins in that case seemingly used a vulnerability in Vingcard locks to enter their target's room, albeit one that required re-programming the lock. "Most probably Mossad has a capability to do something like this," Tuominen says.
